Description

一种载波状态指示方法及设备  Carrier status indication method and device
技术领域 Technical field
本发明涉及通信领域， 尤其涉及一种载波状态指示方法及设 备。 背景技术  The present invention relates to the field of communications, and in particular, to a carrier status indication method and device. Background technique
第三代合作伙伴计划 ( The 3rd Generation Partnership Proj ect , 3 GPP ) 中引入的载波聚合 （ CA , Carrier Aggregation ) 技术， 用户 设备（ User Equipment , UE )可以同时使用多个成员载波（ Component Carrier , CC )进行上和 /或下行通信， 可以提高网络的传输速率和服 务质量， 并在不大幅增加配置带宽的情况下， 保证一般用户的速 率， 同时为一部分用户提供更高的吞吐量。  Carrier Aggregation (CA) technology introduced in The 3rd Generation Partnership Proc ect (3GPP), User Equipment (UE) can simultaneously use multiple component carriers (Component Carrier, CC) The uplink and/or downlink communication can improve the transmission rate and quality of the network, and ensure the rate of the general user without increasing the configuration bandwidth, while providing higher throughput for some users.
载波聚合下的 CC按照承载的功能分为主小区 （ Primary Cell , PCell ) 和辅小区 （ Secondary Cell , SCell ) 。 PCell是工作在主频带 上的小区； UE 在该小区进行初始连接建立过程， 或开始连接重建 立过程， 在小区切换过程中该小区被指示为主小区。 SCell 是工作 在辅频带上的小区， 一旦无线资源控制 （ Radio Resource Control , RRC ) 连接建立， 辅小区就可能被配置， 为 UE 提供额外的无线资 源。 处于 RRC链接态的 UE , 如果没有配置 CA , 则只有一个服务小 区， 即 PCell ; 如果配置了 CA , 则服务小区集合由 PCell 和 SCell 组成。  The CC under the carrier aggregation is divided into a primary cell (PCell) and a secondary cell (SCell) according to the function of the bearer. The PCell is a cell operating on the primary frequency band; the UE performs an initial connection establishment process in the cell, or starts a connection reestablishment process, in which the cell is indicated as the primary cell. The SCell is a cell operating on the secondary frequency band. Once the Radio Resource Control (RRC) connection is established, the secondary cell may be configured to provide additional wireless resources for the UE. If the UE is in the RRC link state, if there is no CA configured, there is only one service cell, that is, PCell. If the CA is configured, the service cell set is composed of PCell and SCell.
其中， SCell 小区可以在初始安全激活流程之后， 通过 RRC 连 接重配置消息激活或者去激活。 当用户设备的业务量较低时， 则可 以释放 （即去激活） 一些 CC , 以避免载波资源的和 CA中用户设备 的电量浪费。  The SCell cell may be activated or deactivated by an RRC connection reconfiguration message after the initial security activation procedure. When the traffic of the user equipment is low, some CCs may be released (ie, deactivated) to avoid wasting power of the carrier resources and the user equipment in the CA.
现有技术中， 提供了用户设备的 SCell 载波激活或者去激活机 制基于媒体接入控制单元 ( Media Access Control Control Element ( MAC CE )和去激活定时（ Deactivation Timers )的结合。 基于 MAC CE的 SCell激活或者去激活操作是由基站控制的， 用户设备可以根 据接收自基站的激活指示获取激活或者去激活信息。 In the prior art, an SCell carrier activation or deactivation mechanism of a user equipment is provided. The system is based on a combination of a Media Access Control Control Element (MAC CE) and Deactivation Timers. The MAC CE-based SCell activation or deactivation operation is controlled by the base station, and the user equipment can receive the Activation of the base station indicates acquisition of activation or deactivation information.
但是， 为了实现载波的实时动态调整， 在进行载波激活或者去 激活时需要达到快速载波选择 ( Fast Carrier Selection , FCS ) , 而 现有技术中通过 MAC CE将载波的激活或者去激活状态指示给用户 设备时， 由于 MAC信令的传输时延难以满足 FCS 的要求； 并且向 每个用户设备逐一指示其载波的激活或者去激活状态， 占用信道资 源， 会导致网络负载加重， 会进一步增加载波的激活或者去激活时 延， 载波激活或者去激活状态的指示效率较低。 发明内容  However, in order to implement the real-time dynamic adjustment of the carrier, fast carrier selection (FCS) needs to be performed when the carrier is activated or deactivated. In the prior art, the activation or deactivation status of the carrier is indicated to the user by the MAC CE. In the case of the device, the transmission delay of the MAC signaling is difficult to meet the requirements of the FCS; and each user equipment is instructed to indicate the activation or deactivation status of its carrier, occupying the channel resources, which will cause the network load to be aggravated, which will further increase the activation of the carrier. Either deactivation delay, carrier activation or deactivation status is less efficient. Summary of the invention

通过上述方案， 用户设备可以从物理下行共享信道获取第一载 波信息， 并根据第一载波信息在载波上进行通信。 相比于现有技术 通过 MAC CE向用户设备指示载波的激活或者去激活状态， 用户设 备从物理下行共享信道获取载波状态的时延较小， 且网络负载较 低。 因此可以减少指示载波激活或去激活状态的时延， 提高载波激 活或去激活状态指示效率。 实施例 5 Through the foregoing solution, the user equipment may acquire the first carrier information from the physical downlink shared channel, and perform communication on the carrier according to the first carrier information. Compared with the prior art, the MAC CE indicates the activation or deactivation status of the carrier to the user equipment, and the delay of the user equipment acquiring the carrier state from the physical downlink shared channel is small, and the network load is smaller. Low. Therefore, the delay indicating the activation or deactivation state of the carrier can be reduced, and the efficiency of indicating the activation or deactivation of the carrier is improved. Example 5
本发明实施例还提供一种载波状态指示方法， 可以应用于基站 通过下行控制信息 （如， DCI format X ) 向用户设备指示载波状态的 过程中， 如图 5或图 6所示， 该载波状态指示方法可以包括：  The embodiment of the present invention further provides a carrier status indication method, which may be applied to a process in which a base station indicates a carrier status to a user equipment by using downlink control information (for example, DCI format X), as shown in FIG. 5 or FIG. The indication method can include:
S501、 基站确定载波的载波状态， 载波状态为激活状态或者去 激活状态。  S501. The base station determines a carrier state of the carrier, and the carrier state is an activated state or a deactivated state.
具体的， 基站可以根据用户设备的 CSI、 小区的负载状态等确 定至少一个载波的载波状态。 其中， CSI 至少可以包括： 信道质量 指示 CQI、 PMI、 秩指示 RI。 其中， 基站确定载波的载波状态的方 法包括但不限于本发明实施例所列举的方法。  Specifically, the base station may determine the carrier status of the at least one carrier according to the CSI of the user equipment, the load status of the cell, and the like. The CSI may include at least: a channel quality indicator CQI, a PMI, and a rank indication RI. The method for the base station to determine the carrier state of the carrier includes, but is not limited to, the methods enumerated in the embodiments of the present invention.
需要说明的是， 本发明实施例中的载波为基站中载波状态能够 发生变化的所有载波。 例如， 若基站中可以包含 5 个载波， 在这 5 个载波中， 3 个载波的载波状态能够发生变化， 则本发明实施例中 的载波为这 3个的载波状态能够发生变化的载波。  It should be noted that the carrier in the embodiment of the present invention is all carriers in the base station whose carrier status can change. For example, if the base station can include five carriers, and the carrier states of the three carriers can be changed among the five carriers, the carrier in the embodiment of the present invention is the carrier whose three carrier states can change.
进一步可选的， 在本发明实施例的第一种应用场景中， 载波状 态指示方法还可以包括： 基站可以向用户设备广播载波序号。  Further, in the first application scenario of the embodiment of the present invention, the carrier status indication method may further include: the base station may broadcast the carrier sequence number to the user equipment.
本步骤 中 ， 基站可以根据至少 一个载波的物理标识符 ( Identifier , ID ) 、 载波的频带和载波的带宽中的至少一项， 为每 个载波配置载波序号， 分别釆用为各个载波配置的载波序号标识各 个载波， 并向用户设备广播该载波序号， 以使用户设备可以根据该 载波序号和载波的载波状态在载波上进行通信。  In this step, the base station may configure a carrier sequence number for each carrier according to at least one of a physical identifier (Identifier, ID) of at least one carrier, a frequency band of the carrier, and a bandwidth of the carrier, and respectively use carriers configured for each carrier. The serial number identifies each carrier, and broadcasts the carrier sequence number to the user equipment, so that the user equipment can communicate on the carrier according to the carrier sequence number and the carrier state of the carrier.
在本发明实施例的第一种应用场景中， 由于现有技术中， 同一 个载波在不同的用户设备中预配置载波序号不同， 例如， 2 个载 波， 分别为载波 A和载波 B , 在现有技术中用户设备 1 中预配置的 1号载波为载波 A , 预配置的 2号载波为载波 B ; 用户设备 2中预配 置的 1 号载波为载波 B。 因此， 在本发明实施例中， 对于同一载 波， 基站可以为各用户设备配置同一载波序号， 该载波状态指示方 法还可以包括 S502 : In the first application scenario of the embodiment of the present invention, in the prior art, the carrier numbers of the same carrier are pre-configured in different user equipments, for example, two carriers, namely carrier A and carrier B, respectively. In the prior art, the number 1 carrier preconfigured in the user equipment 1 is the carrier A, and the preconfigured carrier number 2 is the carrier B; the preconfigured carrier number 1 in the user equipment 2 is the carrier B. Therefore, in the embodiment of the present invention, for the same load The base station may be configured with the same carrier sequence number for each user equipment, and the carrier status indication method may further include S502:
S502、 基站通过广播向用户设备指示所有载波中每个载波的载 波序号。  S502. The base station indicates, by broadcast, the carrier sequence number of each carrier in all carriers to the user equipment.
其中， 载波序号是为每个载波配置的序号， 每个载波的载波序 号不同， 并且载波序号以及载波序号标识的载波对于基站下的所有 用户设备都相同。  The carrier sequence number is a sequence number configured for each carrier, and the carrier sequence number of each carrier is different, and the carrier number and the carrier number identified by the carrier sequence number are the same for all user equipments under the base station.
需要说明的是， 统一的载波序号配置与通过广播形式向每个用 户设备指示载波状态相结合， 可以减少由于基站向不同的用户设备 分别指示载波状态和适用于该用户设备的载波序号相比， 可以减少 信道资源的浪费， 降低网络负载， 并且可以实现载波状态的快速指 示， 进而可以提高载波状态的指示效率。  It should be noted that the unified carrier sequence number configuration and the indication of the carrier state to each user equipment by means of a broadcast may reduce the carrier status respectively indicated by the base station to different user equipments and the carrier serial number applicable to the user equipment. The waste of channel resources can be reduced, the network load can be reduced, and a fast indication of the carrier status can be implemented, thereby improving the indication efficiency of the carrier status.
进一步可选的， S 502 可以替换为 S 502' ： 基站通过专有信令 向用户设备发送所有载波中每个载波的载波序号。  Further optionally, S 502 can be replaced by S 502 ′: the base station sends the carrier sequence number of each carrier in all carriers to the user equipment by using dedicated signaling.
其 中 ， 专有信令可以 为 无线资源控制 （ Radio Resource Control , RRC )信令或者媒体接入控制（ Media Access Control, MAC ) 信令等。  The dedicated signaling may be Radio Resource Control (RRC) signaling or Media Access Control (MAC) signaling.
需要说明的是， 在本实施例中， 载波序号是根据与载波序号相 应的载波的中心频率进行标识的； 和 /或， 载波序号是根据与载波 序号相应的载波的物理标识进行标识的。  It should be noted that, in this embodiment, the carrier sequence number is identified according to the center frequency of the carrier corresponding to the carrier number; and/or, the carrier sequence number is identified according to the physical identifier of the carrier corresponding to the carrier sequence number.
具体的， 由于每一个载波的中心频率都不一样， 因此， 基站可 以釆用载波的中心频率对载波的载波序号进行标识。 例如， 若在激 战中包含 5 个载波， 其载波中心频率分别为： 中心频率 a、 中心频 率 b、 中心频率 c、 中心频率 d、 中心频率 e , 则基站可以将中心频 率 a对应的载波配置为载波 1 , 将中心频率 b对应的载波配置为载波 2 , 将中心频率 c对应的载波配置为载波 3 , 将中心频率 d对应的载 波配置为载波 4 , 将中心频率 e对应的载波配置为载波 5。  Specifically, since the center frequency of each carrier is different, the base station can identify the carrier number of the carrier by using the center frequency of the carrier. For example, if 5 carriers are included in the Guild Wars, and the carrier center frequencies are: center frequency a, center frequency b, center frequency c, center frequency d, center frequency e, the base station can configure the carrier corresponding to the center frequency a as Carrier 1 , the carrier corresponding to the center frequency b is configured as carrier 2, the carrier corresponding to the center frequency c is configured as carrier 3, the carrier corresponding to the center frequency d is configured as carrier 4, and the carrier corresponding to the center frequency e is configured as carrier 5 .
类似的， 由于每一个载波的物理标识都不一样， 因此， 基站也 可以釆用载波的物理标识对载波的载波序号进行标识。 例如， 若在 基站中包含 5 个载波， 其载波物理标识分别为： 物理标识 a、 物理 标识 b、 物理标识 c、 物理标识 d、 物理标识 e , 则基站可以将物理 标识 a对应的载波配置为载波 1 , 将物理标识 b对应的载波配置为载 波 2 , 将物理标识 c对应的载波配置为载波 3 , 将物理标识 d对应的 载波配置为载波 4 , 将物理标识 e对应的载波配置为载波 5。 Similarly, since the physical identifier of each carrier is different, the base station may also identify the carrier number of the carrier by using the physical identifier of the carrier. For example, if The base station includes five carriers, and the carrier physical identifiers are: physical identifier a, physical identifier b, physical identifier c, physical identifier d, physical identifier e, then the base station can configure the carrier corresponding to the physical identifier a as carrier 1, and The carrier corresponding to the physical identifier b is configured as the carrier 2, the carrier corresponding to the physical identifier c is configured as the carrier 3, the carrier corresponding to the physical identifier d is configured as the carrier 4, and the carrier corresponding to the physical identifier e is configured as the carrier 5.

需要说明的是， 基站通过发送指示信息向用户设备指示检测下 行物理控制信道的方式， 用户设备根据基站所指示的检测方式， 从 公共搜索空间中检测下行物理控制信道， 可以减少用户设备的检测 次数， 避免由于用户设备需要进行多次盲检， 延长载波状态的激活 或者去激活时间。 其中， 基站可以通过下行物理控制信道向用户设备指示第一载 波信息， 第一载波信息包括载波的载波状态， 第一载波信息用于使 用户设备根据载波状态在载波上进行通信。 具体的， 如图 5 或图 6 所示， 本发明实施例的方法包括 S 505 : It is to be noted that the base station indicates the manner of detecting the downlink physical control channel to the user equipment by sending the indication information, and the user equipment detects the downlink physical control channel from the common search space according to the detection manner indicated by the base station, thereby reducing the number of detections of the user equipment. To avoid the need for multiple blind checks by the user equipment, to extend the activation or deactivation time of the carrier state. The base station may indicate the first carrier information to the user equipment by using the downlink physical control channel, where the first carrier information includes a carrier status of the carrier, and the first carrier information is used to enable the user equipment to communicate on the carrier according to the carrier status.

进一步可选的， 基站还可以釆用比特位图的方式标识载波的载 波状态， 或者基站还可以釆用统一编码的方式对载波的载波状态进 行编码， 向用户设备指示各个载波的载波状态为激活状态或者去激 活状态。  Further, the base station may further identify the carrier state of the carrier by using a bit bitmap, or the base station may encode the carrier state of the carrier by using a unified coding manner, and indicate to the user equipment that the carrier state of each carrier is activated. State or deactivated state.
其中， 载波的载波状态釆用比特位图的方式进行标识； 或者， 载波的载波状态釆用统一编码的方式进行编码的具体方法可以参考 本发明其他实施例后续相关描述， 本实施例这里不再赘述。  The carrier state of the carrier is identified by using a bit bitmap; or the carrier state of the carrier is encoded by using a unified coding manner, and reference may be made to the subsequent description of other embodiments of the present invention.

当基站向用户设备指示的第一载波信息中包含基站未曾为该用 户设备的载波的载波状态时， 该用户设备可以仅根据该用户设备已 配置的载波的载波状态在载波上进行通信， 忽略第一载波信息中包 含的基站未曾为该用户设备的载波的载波状态。  When the first carrier information indicated by the base station to the user equipment includes the carrier status of the carrier that is not the user equipment, the user equipment may communicate on the carrier only according to the carrier status of the carrier that the user equipment has configured, ignoring the The base station included in one carrier information is not the carrier state of the carrier of the user equipment.
进一步的， 基站也可以根据第一载波信息中包含的基站未曾为 该用户设备的载波的载波状态， 在以前未曾配置的载波上进行通信。 由于基站向用户设备所指示的载波的载波状态的个数多于该用户设 备所能支持的载波个数， 则表明用户设备可以在大于该用户设备聚 合载波能力的多个载波之间切换通信的状态。  Further, the base station may also perform communication on a carrier that has not been configured before, according to the carrier status of the carrier of the user equipment that is not included in the first carrier information.

其中， 载波激活 RNTI 为基站为用户设备配置的用于识别承载 第一载波信息的下行物理控制信道的 RNTI。  The carrier-activated RNTI is an RNTI configured by the base station for the user equipment to identify the downlink physical control channel carrying the first carrier information.
具体的， 用户设备可以在下行物理控制信道的公共搜索空间 中， 根据 RNTI, 解扰下行物理控制信道的 CRC (其中， 基站釆用载波 激活 RNTI加扰 CRC ), 以确定用于传输第一载波信息的下行物理控制 信道。  Specifically, the user equipment may descramble the CRC of the downlink physical control channel according to the RNTI in the common search space of the downlink physical control channel, where the base station uses the carrier-activated RNTI to scramble the CRC, to determine to transmit the first carrier. The downlink physical control channel of the information.
需要说明的是， 在本实施例 中可以先执行 S505 , 再执行 S506-S507 ; 也可以先执行 S506-S507 , 再执行 S505 ; 或者还可以同 时执行 S505 和 S506-S507。 本实施例对 S505 和 S506-S507执行的 先后顺序不做限制。  It should be noted that, in this embodiment, S505 may be executed first, and then S506-S507 may be executed; S506-S507 may be executed first, then S505 may be executed; or S505 and S506-S507 may be simultaneously executed.

S 509、 用户设备根据第一载波信息在载波上进行通信。  S 509. The user equipment performs communication on the carrier according to the first carrier information.
其中， 由于载波序号是根据与载波序号相应的载波的中心频率 进行标识的； 和 /或， 载波序号是根据与载波序号相应的载波的物 理标识进行标识的。 因此用户设备可以根据每个载波的载波序号的 标识 （载波的中心频率和 /或， 载波的物理标识） 在载波状态中确定 用户设备中每个载波的载波状态， 根据载波状态的指示在载波上进 行通信。  Wherein, the carrier sequence number is identified according to a center frequency of a carrier corresponding to the carrier sequence number; and/or, the carrier sequence number is identified according to a physical identifier of a carrier corresponding to the carrier sequence number. Therefore, the user equipment may determine, according to the identifier of the carrier sequence number of each carrier (the center frequency of the carrier and/or the physical identifier of the carrier), the carrier state of each carrier in the user equipment in the carrier state, according to the indication of the carrier status on the carrier.

进一步可选的， 由于第一载波信息包括载波的载波状态， 而载 波状态为激活状态或者去激活状态， 并且基站釆用比特位图的方式 对载波的载波状态进行了标识或者基站釆用统一编码的方式对载波 的载波状态进行了编码。 因此， 用户设备在获取到第一载波信息后， 可以釆用相应的比特位图的方式确定载波的载波状态； 或者， 用户 设备可以釆用统一解码的方式确定载波的载波状态； 载波的载波状 态是基站釆用与统一解码的方式对应的统一编码的方式进行编码 的； 其中， 载波状态为激活状态或者去激活状态。 Further, the first carrier information includes a carrier state of the carrier, and the carrier state is an activated state or a deactivated state, and the base station uses the bit bitmap to identify the carrier state of the carrier or the base station uses the unified coding. Way to carrier The carrier state is encoded. Therefore, after acquiring the first carrier information, the user equipment may determine the carrier state of the carrier by using a corresponding bitmap; or, the user equipment may determine the carrier state of the carrier by using a unified decoding manner; The base station is coded in a unified coding manner corresponding to the unified decoding mode; wherein, the carrier state is an activated state or a deactivated state.
具体的， 用户设备釆用比特位图的方式确定载波的载波状态； 或者， 用户设备釆用统一解码的方式确定载波的载波状态的具体方 法可以参考本发明其他实施例后续相关描述， 本实施例这里不再赘 述。  Specifically, the user equipment determines the carrier state of the carrier by using a bit bitmap; or the specific method for determining the carrier state of the carrier by using the unified decoding manner by the user equipment may refer to the following related description of other embodiments of the present invention.

通过上述方案， 基站可以通过下行物理控制信道向用户设备指 示第一载波信息， 第一载波信息包括载波的载波状态， 以使用户设 备根据载波的载波状态在载波上进行通信。 相比于现有技术通过 Through the foregoing solution, the base station may indicate the first carrier information to the user equipment by using the downlink physical control channel, where the first carrier information includes a carrier state of the carrier, so that the user equipment performs communication on the carrier according to the carrier state of the carrier. Passed compared to the prior art
MAC CE 向用户设备指示载波的激活或者去激活状态， 通过下行物 理控制信道向用户设备广播载波状态的时延较小， 且网络负载较 低。 因此可以减少指示载波激活或去激活状态的时延， 提高载波激 活或去激活状态指示效率。 The MAC CE indicates the activation or deactivation state of the carrier to the user equipment, and the delay of broadcasting the carrier state to the user equipment through the downlink physical control channel is small, and the network load is low. Therefore, the delay indicating the activation or deactivation state of the carrier can be reduced, and the efficiency of the carrier activation or deactivation state indication can be improved.
进一步的， 由于基站向用户设备所指示的载波的载波状态的个 数多于该用户设备所能支持的载波个数， 因此， 用户设备可以在大 于该用户设备聚合载波能力的多个载波之间切换通信的状态。 实施例 6  Further, the number of carrier states of the carrier indicated by the base station to the user equipment is greater than the number of carriers that the user equipment can support. Therefore, the user equipment may be between multiple carriers that are larger than the carrier capability of the user equipment. Switch the status of the communication. Example 6

S601、 基站确定载波的载波状态， 载波状态为激活状态或者去 激活状态。 其中， 本实施例中基站确定载波的载波状态的具体方法可以参 考本发明其他方法实施例中基站确定载波的载波状态的相关描述， 本实施例这里不再赘述。 S601. The base station determines a carrier state of the carrier, where the carrier state is an activated state or a deactivated state. For a specific method for the base station to determine the carrier state of the carrier in this embodiment, reference may be made to the description of the carrier state of the carrier determined by the base station in the other method embodiments of the present invention, which is not described herein again.
需要说明的是， 本发明实施例中的载波为基站中载波状态能够 发生变化的所有载波。 例如， 若基站中可以包含 5 个载波， 在这 5 个载波中， 3 个载波的载波状态能够发生变化， 则本发明实施例中 的载波为这 3个的载波状态能够发生变化的载波。  It should be noted that the carrier in the embodiment of the present invention is all carriers in the base station whose carrier status can change. For example, if the base station can include five carriers, and the carrier states of the three carriers can be changed among the five carriers, the carrier in the embodiment of the present invention is the carrier whose three carrier states can change.

其中， 用户设备可以根据载波激活索引信息快速的从下行物理 控制信道中承载的下行控制信息中获取适用于该用户设备的第一载 波信息可以提高载波状态指示效率。  The user equipment can quickly obtain the first carrier information applicable to the user equipment from the downlink control information carried in the downlink physical control channel according to the carrier activation index information, so as to improve the carrier status indication efficiency.
需要说明的是， 在本实施例中可以先执行 S602 , 再执行 S603 ; 也可以先执行 S603 , 再执行 S602 ; 还可以同时执行 S602和 S603。 本实施例对于 S602和 S603执行的先后顺序不做限制。  It should be noted that, in this embodiment, S602 may be executed first, and then S603 may be executed; S603 may be executed first, then S602 may be executed; and S602 and S603 may be simultaneously executed. This embodiment does not limit the order in which S602 and S603 are executed.

Wherein, the carrier state of all carriers or the carrier state of the carrier whose carrier state changes.
当基站向用户设备指示的第一载波信息中包含基站未曾为该用 户设备的载波的载波状态时， 该用户设备可以仅根据该用户设备已 配置的载波的载波状态在载波上进行通信， 忽略第一载波信息中包 含的基站未曾为该用户设备的载波的载波状态。  When the first carrier information indicated by the base station to the user equipment includes the carrier status of the carrier that is not the user equipment, the user equipment may communicate on the carrier only according to the carrier status of the carrier that the user equipment has configured, ignoring the The base station included in one carrier information is not the carrier state of the carrier of the user equipment.
进一步的， 基站也可以根据第一载波信息中包含的基站未曾为 该用户设备的载波的载波状态， 在以前未曾配置的载波上进行通信。 由于基站向用户设备所指示的载波的载波状态的个数多于该用户设 备所能支持的载波个数， 则表明用户设备可以在大于该用户设备聚 合载波能力的多个载波之间切换通信的状态。 Further, the base station may also perform communication on a carrier that has not been configured before, according to the carrier status of the carrier of the user equipment that is not included in the first carrier information. The number of carrier states of the carrier indicated by the base station to the user equipment is greater than the user setting. The number of carriers that can be supported by the backup device indicates that the user equipment can switch the state of communication between multiple carriers that are larger than the capability of the user equipment to aggregate carriers.
5605、 用户设备根据指示信息， 检测下行物理控制信道， 确定 用于指示第一载波信息的下行物理控制信道。  S605. The user equipment detects the downlink physical control channel according to the indication information, and determines a downlink physical control channel used to indicate the first carrier information.

5609、 用户设备根据第一载波信息在载波上进行通信。  S609. The user equipment performs communication on the carrier according to the first carrier information.
其中， 由于第一载波信息包括载波的载波状态， 而载波状态为 激活状态或者去激活状态， 并且基站釆用比特位图的方式对载波的 载波状态进行了标识或者基站釆用统一编码的方式对载波的载波状 态进行了编码。 因此， 用户设备在获取到第一载波信息后， 可以釆 用相应的比特位图的方式确定载波的载波状态； 或者， 用户设备可 以釆用统一解码的方式确定载波的载波状态； 载波的载波状态是基 站釆用与统一解码的方式对应的统一编码的方式进行编码的； 其 中， 载波状态为激活状态或者去激活状态。 The first carrier information includes a carrier state of the carrier, and the carrier state is an activated state or a deactivated state, and the base station uses the bit bitmap to identify the carrier state of the carrier or the base station uses a unified coding manner.

The carrier state of the carrier is encoded by the base station in a unified coding manner corresponding to the unified decoding mode; wherein the carrier state is an activated state or a deactivated state.
示例性的， 若存在两个对用户设备已配置的载波， 载波 A和载 波 B , 则基站可以釆用比特位图标识载波 A和载波 B , 以向用户设 备载波 A和载波 B的状态信息。 具体的， 基站可以用两比特信息分 别标识载波 A和载波 B的激活去激活状态， 例如高位标识载波 A的 及活去激活状态、 低位标识载波 B 的及活去激活状态。 同 时 " 0" 标识对应载波去激活、 " 1 " 标识对应载波激活。 则 00 表 示去激活载波 A、 去激活载波 B ; 01表示去激活载波八、 激活载波 B ; 10表示激活载波 A、 去激活载波 B ; 1 1 表示激活载波 A、 激 活载波 B。  Exemplarily, if there are two carriers, carrier A and carrier B, which are configured for the user equipment, the base station may identify the carrier A and the carrier B by using a bit bitmap to provide status information of the carrier A and the carrier B to the user. Specifically, the base station can identify the activation deactivation state of the carrier A and the carrier B by using the two-bit information, for example, the high-order identification carrier A and the active de-activated state, the low-level identification carrier B, and the active de-activated state. At the same time, the "0" flag corresponds to carrier deactivation, and the "1" flag corresponds to carrier activation. Then 00 indicates deactivation of carrier A, deactivation of carrier B; 01 indicates deactivation of carrier VIII, activation of carrier B; 10 indicates activation of carrier A, deactivation of carrier B; 1 1 indicates activation of carrier A, activation of carrier B.
相应的， 用户设备则可以根据接收自基站的比特位图的解码方 式， 即 " 0 " 表示去激活， " 1 " 表示激活， 且 " 0 " 和 " 1 " 的顺 序与用户设备预配置的载波序号相同。  Correspondingly, the user equipment can deactivate according to the decoding mode of the bitmap received from the base station, that is, “0” indicates activation, “1” indicates activation, and the order of “0” and “1” is pre-configured with the user equipment.

需要说明的是， 对用户设备已配置的载波不限于本实施例的实 例中所列举的数目 ， 且基站釆用比特位图标识载波状态的方法包括 但不限于本发明实施例所列举的方法， 基站釆用比特位图标识载波 状态的其他方法， 本实施例这里不再赘述。  It should be noted that the carrier that has been configured for the user equipment is not limited to the number listed in the example in this embodiment, and the method for the base station to identify the carrier state by using the bit bitmap includes, but is not limited to, the method enumerated in the embodiment of the present invention. Other methods for the base station to use the bit bitmap to identify the carrier state are not described herein again.
示例性的， 若存在两个对用户设备已经配置的载波， 载波 A和 载波 B , 则基站可以釆用统一编码的方式对载波 A和载波 B的载波 状态进行编码。 具体的， 基站可以选用 4 个不同的数字或者四个不 同的字母或者 4个不同的其他标识对对载波 A和载波 B的载波状态 进行编码。  Exemplarily, if there are two carriers, carrier A and carrier B, which have been configured for the user equipment, the base station may encode the carrier states of carrier A and carrier B in a unified coding manner. Specifically, the base station may encode carrier states of carrier A and carrier B by using four different numbers or four different letters or four different other identifiers.
例如， 基站可以选用 a、 b、 c、 d 四个字母向用户设备指示载 波 A和载波 B的载波状态。  For example, the base station may use four letters a, b, c, d to indicate the carrier status of carrier A and carrier B to the user equipment.
具体的， 基站可以釆用 a代表载波 A和载波 B的载波状态均为 去激活状态； 釆用 b代表载波 A的载波状态为去激活、 载波 B的载 波状态为激活； 釆用 c代表载波 A的载波状态为激活、 载波 B的载 波状态为去激活； 釆用 d代表载波 A的载波状态为激活、 载波 B的 载波状态为激活。 Specifically, the base station may use a to represent the carrier state of the carrier A and the carrier B as the deactivated state; b use b to represent the carrier state of the carrier A to be deactivated, and the carrier state of the carrier B to be activated; Carrier state is active, carrier B carrier The wave state is deactivated; d d means that the carrier state of carrier A is active, and the carrier state of carrier B is active.

需要说明的是， 用户设备中存储有预先设定的比特位图的解码 方式和统一编码所对应的解码方式。 用户设备在接收到釆用比特位 图的方式标识的载波状态后， 则可以釆用预先设定的比特位图的解 码方式对其进行解码； 用户设备在接收到釆用统一编码的方式编码 的载波状态后， 则可以釆用预先设定的统一编码所对应的解码方式 对其进行解码。  It should be noted that the user equipment stores a decoding method of a preset bit bitmap and a decoding method corresponding to the unified coding. After receiving the carrier status identified by the bit bitmap, the user equipment may decode the preset bit bitmap by using a decoding manner; the user equipment is encoded by receiving the unified coding mode. After the carrier state, it can be decoded by the decoding method corresponding to the preset unified coding.
需要说明的是， 对用户设备已配置的载波不限于本实施例的实 例中所列举的数目 ， 且基站釆用统一编码的方式对载波状态进行编 码的方法包括但不限于本发明实施例所列举的方法， 基站釆用统一 编码的方式对载波状态进行编码的其他方法， 本实施例这里不再赘 述。  It should be noted that the carrier that has been configured for the user equipment is not limited to the number listed in the example in this embodiment, and the method for the base station to encode the carrier state by using the unified coding manner includes but is not limited to the enumeration in the embodiment of the present invention. The method for the base station to encode the carrier state in a unified coding manner is not described herein again.
需要说明的是， 由于现有技术中， 不同用户设备所配置的载波 不同， 同一个载波在不同的用户设备中预配置载波序号不同 （例 如， 在基站侧有 3个载波， 分别为载波 A、 载波 B、 载波 C;用户设 备 1 所配置的载波包括： 载波 A和载波 B , 且用户设备 1 中预配置 的 1 号载波为载波 A , 预配置的 2号载波为载波 B ; 用户设备 2所 配置的载波包括： 载波 B和载波 C , 且用户设备 2 中预配置的 1 号 载波为载波 B , 预配置的 2 号载波为载波 C ) , 且在本实施例中并 未对各个载波进行同一标识 （或者排序） ， 因此在本实施例中基站 向每个用户设备指示的第一载波信息不同。 如上述实例， 基站可以 仅仅向用户设备 1指示载波 A和载波 B的载波状态， 向用户设备 2 指示载波 C和载波 B的载波状态。  It should be noted that, in the prior art, different carriers are configured with different carriers, and the same carrier has different carrier numbers in different user equipments (for example, there are three carriers on the base station side, respectively, carrier A, Carrier B, carrier C; the carrier configured by the user equipment 1 includes: carrier A and carrier B, and the pre-configured carrier No. 1 in the user equipment 1 is the carrier A, and the pre-configured carrier 2 is the carrier B; the user equipment 2 The configured carrier includes: carrier B and carrier C, and the pre-configured carrier No. 1 in the user equipment 2 is the carrier B, and the pre-configured carrier No. 2 is the carrier C), and in this embodiment, the carrier is not the same. The identifier (or sort) is therefore different in the first carrier information indicated by the base station to each user equipment in this embodiment. As in the above example, the base station can indicate only the carrier status of carrier A and carrier B to user equipment 1, and indicate the carrier status of carrier C and carrier B to user equipment 2.
进一步的， 由上述可知基站向用户设备所指示的载波的载波状 态的个数多于该用户设备所能支持的载波个数， 则表明用户设备可 以在大于该用户设备聚合载波能力的多个载波之间切换通信的状 态。  Further, it can be seen that the number of carrier states of the carrier indicated by the base station to the user equipment is greater than the number of carriers that the user equipment can support, indicating that the user equipment can be multiple carriers that are larger than the user equipment to aggregate the carrier capability. Switch the status of the communication between.
进一步可选的， 在 S604 之前， 为了保证用户设备可以正确并 实时接收到第一载波信息， 基站可以对用于指示第一载波信息的下 行控制信息进行重复编码， 或者釆用低于常用编码码率的编码码率 对下行控制信息进行编码， 或者重复发送经过编码的下行控制信 息。 Further optional, before S604, in order to ensure that the user equipment can be correct and Receiving the first carrier information in real time, the base station may repeatedly encode the downlink control information used to indicate the first carrier information, or encode the downlink control information by using an encoding rate lower than the common encoding rate, or repeatedly send the information. Encoded downlink control information.
其中， 基站对下行控制信息进行重复编码的具体方法可以参考 本发明实施例 5 中的相关描述， 本实施例这里不再赘述。  For a specific method for the base station to repeatedly code the downlink control information, reference may be made to the related description in the embodiment 5 of the present invention, and details are not described herein again.
其中， 在本实施例中下行物理控制信道可以包括： PDCCH 或 者 E-PDCCH。  The downlink physical control channel may include: a PDCCH or an E-PDCCH in this embodiment.
通过上述方案， 基站可以通过下行物理控制信道向用户设备指 示第一载波信息， 第一载波信息包括载波的载波状态， 以使用户设 备根据载波的载波状态在载波上进行通信。 相比于现有技术通过 MAC CE 向用户设备指示载波的激活或去激活状态， 通过下行物理 控制信道向用户设备广播载波状态的时延较小， 且网络负载较低。 因此可以减少指示载波激活或去激活状态的时延， 提高载波激活或 去激活状态指示效率。 实施例 7  Through the foregoing solution, the base station may indicate the first carrier information to the user equipment by using the downlink physical control channel, where the first carrier information includes a carrier state of the carrier, so that the user equipment performs communication on the carrier according to the carrier state of the carrier. Compared with the prior art, the MAC CE indicates the activation or deactivation status of the carrier to the user equipment, and the delay of broadcasting the carrier state to the user equipment through the downlink physical control channel is small, and the network load is low. Therefore, the delay indicating the activation or deactivation state of the carrier can be reduced, and the efficiency of indicating the activation or deactivation of the carrier is improved. Example 7
